IMPROVEMENT IN OOQKING-STOVES.

(The fitlntnie teftmh in in flgtsz 32mm 33mm ant mating part at thesame.

Be it known that I, J. W. LOWREY, of the city of Dayton, in the countyof Montgomery, and State of @hio,

have invented a new and improved mode of concentrating, distributing andeconomizing heat in Cooking-Stoves, in

using either wood or coal as fuel, the saving of fuel to the extent ofnearly one-half the quantity ordinarilyiused, and the making of thestove air-tight; and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawing making a part of thisspecification, and to the letters of reference marked thereon. i

\The nature of my invention consists in placing in the fire-chamber ofcooking stoves a cast-iron partition, A, chiefly curved, but with aportion of the top and side flat, on which latter portions work thevalves and slide, besidesltwo movable plates at one end to adjust theimprovement, by their extension, to the length of the firechamber of.the stove, whether, shorter or longer, as occasion requires.

In the drawing, the dotted line B C D E F G H K represents thefire-chamber of the stove, B H being the front and top, and Ed? the backand bottom towards the oven of the stove;

L represents an end door of the stove, into which the fuel isintroduced.

M and N are two valves, which are opened or closed according as theregulation or distribution-of the heat,

or its concentration under one or more of the cooking-plates or vesselsmay require.

The slide 0 opens or closes the openings in the back of the innerchamber when itfis desired to pass the heat more directly towards theoven of the stove, or intercept it when elsewhere required. P and Q arethe two movable end-pieces before mentioned. p

What I claim as my invention, and de sire to secure by Letters Patent,is- The inner chamber A, to be inserted into the stove as shown,together with itsregulating-valves and slide M, N, and O, and adjustableend-pieces P and Q, substantially as and for the purposes hereinspecified and described.
